You can generate a note-on event from bash, with something like this: echo -n $'\x90\x45\x70' > /dev/midi01 The above command plays the A note on "/dev/midi01" x90 is the MIDI note-on status byte x45 = decimal 69 = A (440 Hz). x70 is the note velocity If you want to stop the sound, use: echo -n $'\x80\x45\x70' > /dev/midi01 where x80 is the note-off status byte. > For reference I want to be able to generate drone tones on my MIDI.

If you prefer to use ALSA rawmidi devices, replace /dev/midiXX with /dev/snd/midiCxDy, where "x" is the card number and "y" is a device number belonging to this card.
